Re: Houdini's trick
Houdini in play (no analysis!) uses time to fight (tricks). 
Maybe, I can't be friendly, but let me be useful.

Re: Houdini's trick
Even after Rh8 Houdini 3 without tactical mode and with 4CPUs has a hard time seeing Bxh8, I had to increase the number of lines to 14 before it realized it. Unfortunately even the 1CPU mode non-tactical misses Bxh8 in that position:
7R/8/P3k3/1B3p2/1p1b3P/1P2p1PK/5r2/8 b - - 0 1

Re: Houdini's trick
I thought that the bug is playing Rh8 in 0 seconds but houdini3 4 cpu(not tactical mode) suggests it even after more than 10 minutes and does not expect Bxh8
I did not analyze what happens after Rh8 Bxh8 with chess engines and based on my calculation it is an obvious win for white.
After this line
I can calculate a7 and I do not see how black can prevent promotion.
for example
if Ra2 than Ba4 e2 a8Q e1Q Qe8+ wins the black queen
I will think more about it but
I wonder if somebody without computer analysis can see why Rh8 Bxh8 is a draw.

Re: Houdini's trick
2CPU non-tactical also doesn't play Rh8, so maybe it only happens when you use more than 2CPUs:
